Overview: The document is a catalog from Ealing, detailing various optical components and instruments, focusing on optics, opto-mechanics, and mirror mounts.

Optics: This section includes lenses, microscope components, prisms, polarizers, filters, pinholes, mirrors, and beamsplitters, highlighting the variety available for different applications.

Opto-mechanics: Covers rails, mounting hardware, mirror and component mounts, manual and motorized positioners, emphasizing precision and adaptability.

Mirror Mounts: Detailed descriptions of Precise™ Mirror Mounts, Precise™ Thin Optic Mounts, Kinematic Mirror Mounts, and TopAdjust™ Mirror Mounts, each designed for specific applications with features like kinematic design and high-resolution adjustment systems.

Specifications: Includes angular adjustment range, pivot arm length, actuator thread pitch, angular resolution, clear aperture, and maximum component diameter for each mirror mount type.

Applications and Features: Universal mounting designs with features like nylon-tipped locking screws and hex key adjusters. TopAdjust™ mounts are noted for low backlash double ball bearing design, ideal for restricted access areas.

Pricing: Lists prices for each mount type, offering standard and OEM versions for different budgets.

TopAdjust™ Mirror Mounts: Designed for 1 inch and 1.5 inch round optics, top adjustable to prevent beam obstruction, with a 20 mm thick main body for rigidity. Priced at $98.00 for 1.0 inch and $195.00 for 1.5 inch optics.

Beam Steering Devices: Ideal for changing optical centerline height, includes two precise mirror mounts and a 300 mm half-inch post, priced at $329.00.

Fixed Lens Mounts – Threaded: For fixed position mounting of thin lenses, windows, or beamsplitters, priced at $24.00 each.

Polarizer Adapters: Holds cylindrically mounted calcite polarizing optics, priced at $94.00 for 25.4 mm diameter optics.

Filter Holders: Stackable design with spring clips, priced at $32.00 for 50.8 x 50.8 mm filters.

Modular Filter Wheels: Base or post mountable with indexed 6 or 12 position wheels, prices range from $194.00 to $303.45.

Kinematic Prism Platforms: Designed for prisms and beamsplitters, prices range from $59.00 to $64.00.

Rectangular Apertures: Designed with four independent knife-edge blades, available in metric and inch versions.

Mounted Iris Diaphragms: Includes lever operation and continuously variable diameter apertures, priced from $42 to $149.

Unmounted Iris Diaphragms: Offers a range of maximum and minimum apertures, priced between $30 and $104.
